Slow down, and search around b/c the information is buried here. The MATCHBOX is a TOY projector like the name insists. I would go with a D2S projector at a minimum. You will get just better then OEM quality at that.
Theretrofitsource sells an FX35 projector replica kit that outshines OEM projectors (seen it myself!) at a reasonable cost. Cutting Shrouds is easy, and typically the bigger the projector bowl the better the light (typically). So don't be scared of going a little bigger than you expect
It's not as hard as you think, most parts "drop in."
As for painting the housing, the projector itself is made up of a bulb into a reflector bowl into a lens. The OEM reflector housing therefore has no purpose. So you should have no issue PAINTING it at this point, I would advise against "dipping it" as this is something that you don't want to have to access again.
